feat(maps): add kill switches for Google Places autocomplete and details

Add admin toggles for places_autocomplete_enabled and places_details_enabled
alongside the existing places_photos_enabled, all default ON.

- adminService: getPlacesAutocomplete/updatePlacesAutocomplete, getPlacesDetails/updatePlacesDetails
- admin routes: GET/PUT /admin/places-autocomplete, /admin/places-details
- maps routes: autocomplete returns { suggestions: [], source: 'disabled' } when off;
  details returns { place: null, disabled: true } when off
- authService: both flags included in getAppConfig() response
- authStore: placesAutocompleteEnabled + placesDetailsEnabled state and setters
- App.tsx: wire both flags from app-config on load
- AdminPage: two new toggle rows using var(--text-primary)/var(--border-primary) consistent with rest of UI
- i18n: all 15 locales (en, de, ar, br, cs, es, fr, hu, id, it, nl, pl, ru, zh, zhTw)
